A modern SEO audit has two jobs: make sure Google can rank you, and make sure ChatGPT, Gemini and Perplexity actually mention you when a customer asks. This checklist walks through both — eight categories, in the order we'd work them for a small business site.
Most SEO audit checklists you'll find were written for a search world that's quietly changing. They check titles, headings and broken links — all still important — but they say nothing about whether an AI assistant recommends your business when someone types "best plumber near me" or "AI receptionist for a dental practice" into ChatGPT. In 2026, that second question matters as much as the first.
An AI SEO audit covers both. Below is the checklist we work through, grouped into eight categories. You can run most of it yourself with a browser and a few free tools. Work top to bottom — the early categories are the ones that block everything else.
1. Technical foundation (can search engines and AI crawlers reach you?)
If crawlers can't fetch and render your pages, nothing else on this list matters. Check:
- Indexation. Search
site:yourdomain.comon Google and Bing. If key pages are missing, they aren't indexed — find out why before anything else. - robots.txt. Confirm you aren't accidentally blocking Googlebot, Bingbot, or the AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended). Bing matters more than most small businesses realise — it feeds ChatGPT's web results.
- Sitemap. A clean
sitemap.xmllisting your real, canonical URLs, submitted in Google Search Console and Bing Webmaster Tools. - Redirects and canonicals. One clean version of your site (https, one of www/non-www), single-hop redirects, and canonical tags that point to the real URL.
- Core Web Vitals. Mobile load speed and layout stability. Slow mobile pages quietly suppress rankings.
2. On-page SEO (does each page target one clear thing?)
For every important page, check the fundamentals:
- Title tag — unique, under ~60 characters, with the primary phrase near the front.
- Meta description — a compelling ~155-character summary (it won't rank you, but it wins the click).
- One H1 that matches the search intent, with a logical H2/H3 structure beneath it.
- Keyword-to-page match — each page should answer one clear query. Two pages fighting for the same term ("keyword cannibalisation") is a common, fixable problem.
- Image alt text that describes the image plainly.
3. Schema and structured data (can machines read your facts?)
Structured data is how you hand search engines and AI models your facts in a format they can't misread. For a small business, prioritise:
- Organization or LocalBusiness schema on the homepage — name, URL, logo, contact details, and a
sameAsarray linking your social and directory profiles. - FAQPage schema on pages that answer common questions.
- Service or Product schema with clear pricing where you have it.
- Article schema on blog posts.
Validate it in Google's Rich Results Test and fix any errors. If you want the copy-paste JSON-LD, our guide to schema.org for AI search covers the four schemas that move the needle.
4. AI search visibility (do AI engines actually mention you?)
This is the half that legacy audits skip, and it's increasingly where buyers start. The test is simple to describe and revealing to run: open ChatGPT, Gemini and Perplexity, and ask the real questions your customers ask — "best [your service] in [your town]", "who should I hire for X" — and note whether your business appears.
If you show up in fewer than two of every ten answers, you're effectively invisible to AI search. That's not a niche concern any more — it's the fastest-growing way people find local services. We cover the how and why in what AI search visibility actually means and the common causes in why your business is invisible to ChatGPT.
5. GEO and AEO (is your content built to be quoted?)
Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO) are about structuring content so an AI can lift a clean, correct answer out of it. Check that your key pages:
- Answer the question in the first paragraph, then expand — not the other way round.
- Use clear question-style headings that match how people ask.
- State facts plainly and self-containedly (an AI quoting one paragraph shouldn't need the rest of the page for context).
- Include specifics — prices, timeframes, locations — rather than vague marketing language.
New to the terms? Start with how GEO differs from SEO.
6. Entity and topical authority (does the web agree on who you are?)
Search engines and AI models build a picture of your business from consistent signals across the web. Audit:
- NAP consistency — your Name, Address and Phone number identical across your site, Google Business Profile, and directories.
- Topical depth — do you have a genuine cluster of content on your core service, or one thin page? Depth on one topic beats shallow coverage of five.
- Google Business Profile — complete, verified, categorised correctly, with recent reviews.
7. Off-page and authority (does anyone vouch for you?)
Links and mentions from other reputable sites remain one of the strongest ranking signals — and for a new domain, usually the limiting one. Check:
- Your Domain Rating / Authority versus the sites already ranking for your terms. A brand-new site with near-zero authority won't outrank established competitors on competitive keywords, no matter how good the page is — so target easier, long-tail queries first while authority builds.
- Backlink quality — a handful of relevant, editorial links beats hundreds of low-quality ones.
- Unlinked mentions — places that name your business but don't link; often easy wins.
8. Content and freshness (is anyone being served stale or thin pages?)
Finally, review the content itself: thin pages that say little, outdated posts with old years or dead offers, and gaps where customers clearly have questions you haven't answered. Update, consolidate, or expand — and make sure every important page has a clear next step for the reader.
How to turn the checklist into a plan
Working through all eight categories by hand is a solid afternoon's work, and the AI-visibility probes in particular are fiddly to do manually across several engines. That's exactly what our free AI SEO audit automates — it runs the checks across all eight categories, tests whether AI engines mention you, and returns a prioritised report with ready-to-paste fixes and a 30-day plan. No signup, one free audit per business.
Whether you use the tool or work down this list by hand, the order is what matters: fix the foundation first, earn authority patiently, and build your content around one topic deeply enough that both Google and the AI engines can tell exactly what you're the answer to.
